i have a 71 340 ,80 over with 13-1 piston and running ported x heads with weiand tunnel ram AED750 dp
and would like to replace 360 in durango
and want to know if the 99 5.9 magnum heads will interchange ,if sowill the magnum heads give me any performance edge .
only reason using the magnum heads is
planning to put motor in my durango and wanted brackets for 99 alternator and pulley system to fit on motor
will try to use oem fuel system from durango
can i mate it with the ecu and factory fuel inj? and timing
and how?
i take it, new injectors and throttle body will be needed ,how big?
will ecu handle changes?
can i run carb system and keep ecu?
